Elbow silencers - Model 123 industrial grade, all welded construction - dB Noise Reduction

 

Applications

  • Fan inlet and outlet silencers
  • Pressure blower silencers
  • Intake silencers on gas turbine systems
  • Ventilation intake and discharge silencers
  • HVAC duct silencers

Benefits

  • Designed to match the dimensions of the connecting equipment or ductwork
  • No transitions or plenums required
  • Much higher attenuations than straight through silencer designs due to acoustic elbow effect
  • Aerodynamically designed long radius elbow baffle passages (CR = 0.5) for minimum pressure drop

Accessories

  • Galvanized and stainless steel mesh bird, insect and safety screens
  • Flanges match drilled to connecting equipment or ductwork
  • Mounting brackets, support legs, saddles and feet for silencer installation
  • Access panels and doors for inspection of internals
  • Variety of fabric, film and mesh baffle liners available for different types of service
  • Pressure and flow measurement devices including pressure taps, rings and piezometer tubes

Design options

  • Cleanable/removable baffle designs for dirty applications including special silencers that can be serviced in-situ
  • Tapered transition/evase silencers for attenuation in restricted spaces
